New Z or TT my 370?

Spooler

The VQ with a quality TT kit is more reliable. The VR30's have issues stock from all of what I am hearing. If the OP wants 700whp or more then a VQ is where he needs to be.

They are direct injected right? I'm always seeing Sebastian @specialty posting pics of before and after cleanings... apparently gets nasty in there because of the direct injection.

I would be keeping the same motor and would be going through Sebastian at Specialty Z for the work. I plan to keep the whp to high 400's as I don't need that kind of power and want minimal wear on the engine. Mine is a daily driver with occasional track usage.

So I kinda relate to where you are coming from - the decision is even harder due to the new Z coming out. On one hand - to do the boosting - one is looking at $20k for doing it right with a shop or going the router of getting a new Z and having the R&D already done on the car - and I’m sure adding a Dp and a tune will get you your gains you’re looking for in a very reliable package.

One question is this - would you consider holding off on TTing your Z till the new Z comes out - and then a few years later. Reasons being are 1. You get to see the new Z in person and see what the aftermarket community can do with the platform and 2. Give it another 3yrs and you’ll probably be able to buy a slightly used Z for a considerable discount (bc sports cars don’t hold their value).

Is there any other cars that you are considering - such as the Supra with a MT? Regardless - I am in the same boat - do I keep the current Z and boost it or just get a newer platform and boost that?

Talk with Seb and see what he says.

You'd fit right in in Austin

I'm in CA so I'm cautious about planning a tune for the new Z as I'm not sure it will pass smog. I wouldn't need to worry about it for the first 6 years, though, so it would be down the road. Having a factory TT setup would be reassuring, though. I also like the look of the '09 370 that I have. Adding all the bolt-ons back on with a clearbra for the new one would definitely put me in the neighborhood of $65k+ so it's a pretty big price point difference as well.

This is a tough call. I'd really like to have a feel for overall engine longevity for this decision. I've kept the car in very good condition and the inside is in outstanding shape. Given I installed the Workshop 12 tablet as well I'm not too worried about the infotainment head unit, either. I would actually be downsizing for the new Z.

You can't.

Nah. Austin is a terrible city to move to.

Austin is not what it used to be.

TX is too damn hot.

TT 370 would be the way to go if you're looking for big power. If i got a new Z, I would likely only do suspension and a cat-back. Kinda done with the heavy tuning game lol.

Yeah, a lot of my family is in Texas. I like a fair number of things about Texas but the weather is definitely not one of them. I'm definitely planning on going light on the FI if I do upgrade the 370.

It's a difficult decision, to be sure. I don't think I would wait that long. In 3 or 4 years, I think this decision would start to lean heavily towards a new car but right now I feel like there are a lot of years left in my current Z. I am rather sentimental towards the Z line so I would probably stick with the current one or the new model.

I've been wanting more power for a number of years now. Not crazy power mind you, but enough to feel it. I stopped tracking my car a few years ago as I got frustrated with keeping up with folks in the corners but getting blown away on the straights.

Part of me wants to wait to see the new Z but then again I've watched quite a few review videos, hands-on trials and countless photos so I think I know what I would be getting. My interior is in as good of shape as the new Z and my current screen is larger and more functional. My seats are in great condition and the new Z is really using most of the same or similar plastics as the current 370. So I would be paying $60'ish to get a 400hp TT at the crank, which probably is going to translate to what, 340-360 at the wheel? I've got 317 at the wheel now (at least that was a few years ago on the dyno) so it wouldn't be a huge gain.

Its actually much more. For example Fast Intentions TT kit will put you ~15K, don't even think a proper fuel return set up is there. So another 1-1500 in fuel upgrade. Build bottom end will put you 10K. Tuning.. 1-2K. Clutch/flywheel upgrade, 1-2K. Labor for all, no clue. close to 10K?

I'm in the same boat as well. I'm planning to go TT on my 14 Nismo. Just got a low mileage full block to start with.

Elmo370z

Just swap in a vr38. I can get you a brand new long block for 13k

ocfoilist

The GT-R engine? Interesting...does that really just drop into a 370? What is involved with an engine swap like that? That's about 500-550hp, right?

Yes gtr engine. Drops in with some modifications to make everything work. If you’re going to spend money on a FI TT Kit with supporting mods. Vr38 makes the most sense.
